Question

Reproductive cells of sponges are formed from

• A. Pinacocytes
• B. Choanocytes
• C. Archaeocytes
• D. Trophocytes

Answer 1

The correct option is C Archaeocytes

Sponges reproduce both asexually and sexually. The asexual reproduction is through regeneration, budding and branching, fission & fragmentation and formation of gemmules. In budding, numerous archaeocytes gather near the surface resulting in a small outgrowth on the pinacoderm, and during gemmule formation, archaeocytes laden with glycoprotein or lipoprotein get aggregated into a mass. Sexual reproduction involves the formation of sperms and ova. The sex cells arise from archaeocytes which are totipotent cells.

Hence the correct option is C.
